Sick leave among healthcare workers increased with each COVID-19 vaccine dose. mRNA-1273 led to more frequent and longer absences after the third dose, risking healthcare system strain.
Area of Science:
- Infectious Diseases
- Public Health
- Occupational Health
Background:
- COVID-19 vaccination is crucial for controlling SARS-CoV-2.
- Healthcare worker (HCW) vaccine-related sick leave poses a risk to healthcare systems.
Purpose of the Study:
- To analyze sick leave and medication use post-COVID-19 vaccination in HCWs.
- To compare sick leave patterns after first, second, and third vaccine doses.
Main Methods:
- Prospective cohort study (CoVacSer) involving 1704 HCWs.
- Data collected via electronic questionnaires on sick leave and medication.
- Analysis of sick leave following BNT162b2mRNA and mRNA-1273 vaccines.
Main Results:
- 34.9% of HCWs experienced sick leave after at least one vaccination, totaling 1550 sick days.
- Sick leave duration and frequency increased with each successive vaccination.
- mRNA-1273 resulted in significantly longer and more frequent sick leave after the third dose compared to BNT162b2mRNA.
Conclusions:
- Booster vaccinations may lead to staff shortages, impacting healthcare system capacity and patient care.
- Findings can inform vaccination strategies to mitigate workforce disruptions.
- Proactive planning is needed to manage post-vaccination absences during future COVID-19 waves.
